CTP synthases also form filamentous structures of different morphologies known as cytoophidia, whose functions in most organisms are unknown. In mammalian cells, there are 2 isozymes of CTP synthase, that is, CTPS1 and CTPS2. Cytidine triphosphate synthase catalyzes the synthesis of cytidine 5'-triphosphate (CTP) from uridine 5'-triphosphate (UTP), the final step in the production of cytidine nucleotides. Other names CTP; Cytidine-5'-triphosphate; Cytidine 5'-(tetrahydrogen triphosphate) Cytidine 5′-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP using either ammonia or l-glutamine as the source of nitrogen. cytidine triphosphate synthetase: Abbreviation Variation Long Form Variation ...

However, the … N2 - Cytidine triphosphate (CTP) synthase is one of the key enzymes in pyrimidine nucleotide anabolic pathways. Interestingly, induction of the formation of CTP synthase filament is responsive to starvation or glutamine depletion. cytidine triphosphate synthase ELISA Kits The ELISA (enzyme-linked immunosorbent assay) is a widely used application for detecting and quantifying proteins and antigens from various samples. Recently, cytidine-5'-triphosphate (CTP) synthase was discovered to form a filamentous structure that is evolutionarily conserved from flies to humans. is synthesized from uridine triphosphate by CTP synthase.

This reaction is important for the biosynthesis of nucleic acids, playing a key role in lymphocyte function and turnover. CTP plays a central role in nucleotide and lipid biosynthesis and is synthesized de novo by the catalytic action of CTP synthase (CTPS). It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite.

Fly: Vol. In a cytidine deaminase-deficient mutant, which cannot convert cytidine to uridine, cytidine was able to repress CTP synthetase but was no longer able to repress genes of thepyr operon. cytidine 5'-triphosphate synthase 2. Regulation of Human Cytidine Triphosphate Synthetase 2 by Phosphorylation. ABSTRACT. Abstract Cytidine triphosphate (CTP) synthase is one of the key enzymes in pyrimidine nucleotide anabolic pathways. CTPS mediates the conversion of uridine triphosphate into cytidine triphosphate. CTPS1, one of two mammalian CTP synthases (the other being CTPS2), catalyzes the formation of CTP, an essential nucleotide for DNA and RNA synthesis (Veillette and Davidson 2014). Its deficiency may result in mutator effects and multidrug resistance. CPEC is activated by phosphorylation in cells and metabolized to cyclopentenyl cytosine 5′-triphosphate (CPEC-TP). 108-114. CTPS is an important modulator of lymphocyte proliferation and has been identified as a potential therapeutic target for the treatment of acute lymphoblastic leukemia. The enzyme, encoded by the CTPS1 gene, is important in the biosynthesis of phospholipids and nucleic acids, and plays a key role in cell growth, development, and tumorigenesis (summary by Thomas et al., 1989). How to abbreviate Cytidine Triphosphate Synthase 1?
